K346B - Lincoln Electric NA-5S Wire Drive Assembly 95:1 Gear Ratio

Precision Wire Feeding for Automatic Systems

The Lincoln Electric K346B Wire Drive is a critical component designed to power NA-5S automatic wire feeding systems. Engineered for heavy industrial applications, this unit features a robust 95:1 gear ratio, providing the necessary torque and control to feed solid electrode wires ranging from 1/16 inch to 3/32 inch (1.6-2.4 mm). This specific gear ratio strikes an optimal balance between torque and speed, allowing for a maximum wire feed speed of 456 inches per minute (IPM). This capability makes it an excellent choice for high-deposition welding tasks where consistency and reliability are paramount.

Designed primarily for Submerged Arc Welding (SAW) applications, the K346B comes fully equipped with essential accessories to streamline your setup. It includes a flux hopper, which is vital for managing the granular flux used in the SAW process, and a wire straightener to ensure the electrode enters the weld puddle precisely. The inclusion of these components reduces the need for separate sourcing and ensures compatibility right out of the box. The unit connects directly to the NA-5S control via the included 4-foot motor and flux hopper cords, facilitating a straightforward installation process.

It is important to note that this specific model does not feature high-frequency insulation. It is intended for standard starting methods typical of submerged arc and specific automatic MIG processes. By integrating the K346B into your automation setup, you ensure that your welding operations benefit from Lincoln Electric's legacy of durability and precision performance. Whether utilized in beam fabrication, tank manufacturing, or pipe mills, this wire drive assembly delivers the steady feed required for defect-free welds in demanding environments.
